HEAD-GATE.

To all whom t may concern Be it known that we, HENRY L. ZIEGLER and JOHN P. ZmGLER, citizens of the United States, residing at New Bridge, in the county of Baker and State of Oregon, have invented new and useful Improvements in Head-Gates, of which the following is a specification.

This invention relates to head gates for controlling the flow of water in irrigation ditches and the like,and the principal object of the invention is to produce a gate )f simple and effective construction whereby the flow of water will be automatically regulated.

A further object of the invention is to provide the gate with an adjustable pressure board, whereby the pressure of the water passing the gate may be regulated and maintained constant.

VA further object of the invention is to provide simple and effective means for automatically adjusting and controlling the pressure board to compensate for the slight delays occurring when the gate starts to rise or to fall, owing to the change of level in the ditch or stream in connection with which it` is used.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may 6e resorted to when desired.

In the drawings,-Figure 1 is a top plan view of a device constructed in accordance with the invention. Fig. 2 is a vertical sectional view talen longitudinally through the device on the line 242 in Fig. 1. Fig. 3 is a vertical transverse sectional view taken on the line 3-3 in Fig. 1. Fig. 4 is a perspective detail view showing one side of the main frame 3. Fig. 5 is a perspective detail view showing a portion of the verti- Specicaton of Letters Patent.

cally slidable gate frame. Fig. 6 is a sectional detail view taken on the line 6 6 in Fig. 3.

Corresponding parts in the several figures are denoted by like characters of reference. ,v

Referring to the drawings, 1 designates a box or casing which is in communication with a source of water supply, such as a ditch or stream, so that the water level in said box or casing will be controlled by such source. The box is provided with a flume or outlet 2 having a frame 3 which is tightly connected with the box so as to prevent leak.- age. The frame 3 includes uprights 4 which are grooved or otherwise constructed to constitute guides for the vertically slidable gate frame 5 which is equipped with roller bearings 6 engaging the uprights 4 so as to enable the vertically movable gate frame to operate freely and without undue friction.

The movable gate frame 5 is provided with guides 7 for the 'vertically adjustable float frame B which includes side members or uprights 8 that operate in the guides 7 and which are connected together by cross bars 9, 10, the latter of which is extended beyond the side members to support the flo-ats l1 which are suitably connected therewith.

The frame 3 supports at the bottom thereof a baseboard 12, the upper edge of which is at the level of the bottom of the ditch or stream which constitutes the source of suply. p The vertically movablegate frame 5 carries the gat-e 13, the upper edge of which is about level with the upper edge of the board 12 when the frame 5 is at the downward limit of its movement.

An extension gate 14` is provided which, when the frame 5 is in a lowered position, is accommodated between the gate 13 and the baseboard 12. The lower edge of the gate 13 is provided with a flange 15 which when the gate moves in an upward direction is adapted to engage a corresponding flange 16 on the extension gate 14, which latter is thus capable of rising with the gate carried by the frame 5 for the purpose of obstructing passage of water through the lower part of the frame 3. The side members or up sof rights of the frame 3 are grooved for the accommodation of the extension gate 1111 and a hooked rod 17 rising `from the sill of the frame 3 is adapted to engage a flange 18 at the lower edge of the extension gate 14 for the purpose of limiting the upward movement thereof.

For the purpose of effecting proper adjustment of the float frame B with respect to the gate frame 5, the side members or uprights 8 of said lioat frame may be provided with racks 19, said racks being engaged by the cog wheels 20 on a shaft 521 which is supported for rotation on the gate frame and which may be rotated by means of a suitable crank 22. Any suitable well known locking means may be used for the purpose of maintaining the float frame at the desired adjustment with respect to the gate frame.

The side members of the gate frame are grooved for the reception of a pressure board 23 having on the face thereof a rack 24;. The lower edge of this pressure board, when the latter is in its lowermost position, coincides with the upper edge of the gate 13 and fits tightly thereon so as to obstruct the passage of water. The pressure board, however, may be raised so as to permit water to overflow the gate and to regulate and control such overflow. To effect the desired adjustment of the pressure board, a vertically slidable bar 25 is mounted in suitable keepers 26 on the cross bars 9 and 10 of the iloat frame, said bar being capable of being secured at various adjustments by a pin or screw 27.

Hingedly connected with the lower end of the bar 25 is an arm 28 carrying a float 29. Said arm is also provided at one end thereof with a toothed segment 30 meshing with the rack 211. It will be seen that by adjusting the sliding bar 25, the segment 30 being in mesh with the pressure board, the latter may be raised or lowered to the desired position with respect to the upper edge of the gate 13. An independent and automatic adjustment of the pressure board will be effected by the rise and fall of the float 29 on the arm 28, the pressure board being lowered and raised by such rise and fall, as will be very evident.

In the operation of this invention, the float frame may be adjust-ed with respect to the gate trame so as to maintain the upper edge of the gate 1'3 constantly in a predetermined position with respect to the water level. The quantity of water permitted to pass over the gate, as well as the pressure of such water, may be determined by proper' adjustment of the pressure board. At times when the gate frame, under the influence of the floats, starts to rise or fall owing to a change in the water level there is apt to be a slight del-ay caused by friction, but the irregularity caused by such delays will be counterbalanced by the float 29 which when `the water falls below the predetermined level, the float 29 will operate to raise the pressure board, thereby increasing the area of the escape opening. As soon as the gate vframe acts properly under the influence of the floats 11, normal conditions will be restored.

The box or casing l is to be made of suitable dimensions to accommodate the floats of the device, said ii'oat-s and other mechanism of the gate being thus protected from injury by floating wood or other material carried by the irrigating water.

Having thus described the invention, what is claimed as new, is:-

1. In a device of the character described, a guide frame, a gate frame supported for vertical movement thereon, and a float frame mounted on the gate frame for vertical adjustment with respect thereto.

2. In a device of the class described, a guide frame having a baseboard, a gate frame vertically movable on j the guide frame, an extension gate supported movably by the guide frame, said gate and extension gate having interengaging flanges, and a float carrying frame associated with the gate frame.
